Genome-wide gene-deletion screening identifies mutations that significantly enhance explosives vapor detection by a microbial sensor.

Abstract excerpt

Genetically engineered microbial biosensors, capable of detecting traces of explosives residues above buried military ordnance and emitting an optical signal in response, may potentially serve for the standoff detection of buried landmines. A promising candidate for such an application is a previously reported Escherichia coli-based reporter strain that employs the yqjF gene promoter as its sensing element;...
